BICYCLE-WHEEL TIRE.

SPECIFICATION forming part of Letters Patent No. 684,712, dated October 15, 1901. Application tiled February 27, 1901` Serial No. 49,027. (No model.)

To @ZZ whom it may concern:

Be it known that I, CHARLES, HERMAN PASCHKE, a citizen of the United States, and a resident of Buialo, in the county of Erie and State of New York, have invented a new and Improved Bicycle-lVheel Tire, of which the following is a full, clear, and exact description.

This invention relates to the tires of bicycle-wheels or Wheels of other vehicles which it is essential shall be measurably elastic.

The object of my invention is to provide a resilient wheel-tire of novel construction which is practical and durable and that may be produced at moderate cost.

The invention consists in the novel construction and combination of parts, as is hereinafter described,and defined in the appended claims. I

Reference is to be had to the accompanying drawings, formin ga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view in part of a bicycle-Wheel having the improvements. Fig. 2 is an inverted plan view of the same. Fig. 3 is a transverse section substantially on the line 3 3 in Fig. 1. Fig. a is alike view on the line 4 a inIFig. l. Fig. 5 is a partly-sectional side View of a portion of the improved tire, showing a novel supporting and clamping device for the tire-sections. Fig. 6 is a transverse sectional view substantially on the line 6 6 in Fig. 5. Fig. 7 is a longitudinal sectional view of a novel coupling for a springwire ring employed, taken opposite the arrow ai in Fig. 2. Fig. 8 is a transverse sectional View showing a slightly-changed construction of details represented in Fig. 3. Fig. 9 is a transverse sectional View substantially on the line 9 9 in Fig. 10. Fig. 10 is a side view in part of the bicycle-wheel rim, a portion of a tension Wire ring employed, and an end view of a transverse clamp that engages duplicate tension wire rings held oppositely upon the Wheel-rim. Figs. 1l, 12, 13, and lat are side views of modified forms of spacing-blocks employed. Fig. 15 is a side view of a portion of a vehicle-wheel, showing a ,modified construction ofthe resilient tire and a modified form of the tire-supports which hold the tire-sections concentric with the wheel-rim.

dispose wire spacing-coils therefor exteriorly of the gum tire-sections and adapt said coils to serve as the tread of the tire. Fig. 18 is a transverse sectional view of details substantially the equivalents of those showin in Fig. 17, but having the resilient supports of the tire formed of strips of elastic metal instead of wire; and Fig. 19 is a detached and partlysectional face view of one of the spacingblocks preferably employed for the resilient tire shown in Figs. 15 and 16.

In the drawings which represent the construction and application of the invention upon a vehicle-wheel, and particularly upon one of the traction-wheels for a bicycle or the like, 2O indicates a portion of the rim of such a wheel, and 2l the spokes of the wheel, that in complete form hold the rim concentric with the hub thereof, as usual. The tire proper maywith advantage be formed ofa plu rality of tread-sections of elastic material, either vulcanized gum or resilient-wire coils.

In the several figures where the gum treadsections 22 appear it will be seen that cach of said tread portions has a peculiar shape, comprising a solid rib having a convex treadface, and at each side of said rib a similarintegral flange ct is laterally extended. Between the true ends of each adjacent pair of tread-sections 22 a spacing-block 23, preferably of metal, is introduced, these blocks of suitable thickness each having parallel side faces and a peripheral formation that may be somewhat varied-ens, for example, the spac` ing-blocks may with advantage have a laterally-elongated and substantially rectangular form when used in connection with the gum tire-sections 22, the upper corners of the blocks being reduced and rounded, as shown in Figs. 3, 4, 6, and 8. The series of gum` tread-sections 22 are held circularly arranged together, with a suitable number of spacing# blocks 23 intervening their ends by two pairs of wire rings 24 24C and 25 25, the latter pair being termed carrier-rings and the other pair binding-rings, to be hereinafter described. The rings 25 pass through two IOO . shown in Figs. l, 2, 3, 15, and 17.

concentrically upon the wheel-rim 20.

spaced perforations formed in each block 23, near the lower edge thereof, and upon said wire rings the flanges a of the gum tread-sections are seated. The ends of each carrierring 25 are cut to taper them, and these portions have a lapped engagement with each other, as clearly shown in Fig. 5. The pre-- v ferred means for holding the lapped ends of the carrier wire rings 25 suitably clamped, so as to permit the ends of each ring tohave a limited slidable movement endwise on each other, is clearly shown in Figs. 5 and G and consists of a spacing-clamp 26, formed of a single piece of plate metal having its ends lapped, so as to have bearing on the central portion, and provided with two spaced tubulations b for the reception of the lapped ends of the wire carrier-rings 25.

"Phe ends of the plate material forming the spacing-clamp 26 are secured upon the intermediate portion by rivets or the like, as indicated in Fig. o', the width of the plate material forming the clamp being sufiicient to receive in the tubulationsa cylindrical body portion of each end of a carrier-ring, thereby producing a reliable guide-box for the engaged ends of each carrier-ring.

As represented in Fig. 5, two spacing-blocks are disposed, respectively, at the side edges of the tubulated clamp 26, a short section of the gum tread 22 fitting between these two blocks and having its iianges a seated upon the tribulations b, as best shown in Fig. 6, this construction affording a continuous ring when the parts are assembled.

The diameter of the sectional tread-ring for the wheel-tire is so proportioned to that of the rim 20 as to atford an annular space between said parts, and upon the outer face of the rim 2O a shoe 2Ou is imposed, which may be in ring form or, if preferred, may be formed of several spaced segments, as represented in Fig. 10. The shoe or shoes 20L each consists of plate metal having concavities or tubulations along the side edges thereof and a flat intervening portion which seats upon the outer face of the tire-rim 20, to which the shoe or shoes are secured by bolts c, as shown in Figs. 3, 8, 9, 10, and 16. In the tubulations of the shoe-sections 2Oa two similar wire tension-rings 27 are held loosely, and each one is drawn taut by mea-ns of a clamping device 28, as indicated in Fig. l.

At suitable intervals a plurality of similar resilient bracket-arms 29 are introduced between the carrier-rings 25 and the tensionrings 27, so as to connect them in an elastic manner and hold the tread portion of the tire The bracket-arms 29 may be formed either of pliable bands of gum fabric or cloth or of laterally-elastic metal strips, as indicated in Figs. 8, 1G, and 18, or spring-wire rods, as When elastic wire is employed as a material for the bracket-arms 29, said arms each consists of a strand of wire bent into loop form near the center of length, so as to engage the loop with the body of one of the tension Wire rings-27, and seat said loop in the concavity or tubulation of an adjacent end of a shoesection 20, as indicated in Figs. 3 and 16. Usually the bracket-arms 29 have their end portions extended upward from the loop thereon, and said ends are then wrapped around an appropriate tension wire ring 27, as shown in Figs. 1 and 2. It is preferred to locate the bracket-arms 29 oppositely in pairs, so that they will support the tread portion of the tire at like points on the wheel-rim, as shown in Fig. 2.

The spacing-blocks 23 each has two perforations formed therein above the perforations which receive the carrier-rings25,and through these u pper perforations the two similar binding-rings 24 are inserted, having bearing contact with the upper surfaces of the flanges d on each gum tread-section 22. The bindingrings 2l have one end of each secured by any suitable means within a perforation in one of the spacing-blocks 23, and directly above this secured end of the binding-ring a perforation is formed in the spacing-block for the loose insertion therethrough of the other end of said binding-ring, as clearly shown in Figs. 1 and 5.

To provide means for retaining the block 23 in position, so as to prevent improper endwise movement of the gum tread-sections 22 on the carrier-rings 25, a Wire core-ring 30 may be inserted loosely through perforations in the spacing-blocks 23, formed between the perforations that receive the carrier-rings, and between each pair of spacing-blocks 23 a wire coil 31 is mounted upon the core-ring 30, having the ends thereof pressed against the pair of blocks, as shown in Fig. 2.

The block 26, that has already been described as serving to clamp the ends of the carrier-rings 25 in slidable engagement, is also provided with two spaced holes e, wherein hooks d, formed on the ends of the corering 30, are hooked and the ring thus drawn taut, and as the block 26 has its ends impinged against two adjacent spacing-blocks 23 it will be evident that the coil-sections 31 will prevent an improper movement of the spacingblocks and tread -section between which they are located. Should it be preferred to utilize strips of elastic metal in the formation ofthe spring bracket-arms 29, such strips may each be bent-to provide two spaced loops g thereon for engagement with the rings 25 and at the center of said strip have another loop g' formed, as shown in Fig. 8. In this modied construction of thev spring bracketarms the loop g' is perforated to receive a bolt c and, as shown, provides two laterally-resilient arm members at each side of each carrierwire 25, having sufticient length to properly space said rings from the tension-rings 27,

ywhereon the bent end portions of the metal strip composing the bracket-arm have hooked engagement and also a lapped engagement IOO IIO

with each other and with the upper side of the tire-rim 20, upon which thc bracketarm is held by the bolt c, thatpasses down through perforations in the rim, which aline with the perforation in the loop g. As before mentioned, the series of spacingblocks which intervene the tread-sections of the improved tire may be considerably changed in construction within the scope of the invention-as, for instance, each block may be circular, as shown at- 23n in Fig. 1l, pentagonal, as shown at 23b in Fig. 12, ociagonal, as shown in Fig. 13 at 23, or rectangular, as shown in Fig. 14 at 23d, suitable perforations or indentations being formed in or on such spacing-plates to receive the wire rings employed for supporting tread-sections of the tire.

In Figs. 15 and 1G is shown an ad vant-ageous construction of the improvementa wherein wire coils 22L are substituted in place of the gum tread-sections 22, and in said figures and Fig. 10 is shown another modification 23e of the spacing-blocks that may be employed with the coiled-wire tread-sections 22,

It will be seen that the spacingblocks 23 each consists of two nearly-circular plates having ears h laterally formed thereon to receive rivets or screws which hold said plates clamped upon an intervening` cushion-piece c'. The spacing-blocks 23e are mounted upon the four wire rings 2i 24E and 25 25 in sufficient number to hold the coiled-wire treadsecticns 22 spaced apart and in compressed condition. In this construction of the improvement it is preferred to use resilient-wire bracket-arms for connection of the carrierrings 25 with the tension-rings 27, said arms having a looped engagement with the tension-rings, and then extending two spring members of each arm to have a hooked and secured engagement upon an appropriate carrier-ring, these hooked ends of the arms entering recesses formed at proper points between the two spaced plates of each composite spacing-block 23, said recesses being each produced by cutting a notch m in the elastic cushion-piece e', as shown in Fig. 19.

In Figs. 17 and 1S a different arrangement of parts is shown which adapts the spacing wire coils 31 to become the tread for the tire, to effect which it is only necessary to reverse the position of each gum tread-section 22, so that the body portion will project down between the carrier-rings 25, the binding-rings 2e then bearing upon the previously lower faces of the flanges a. 1i may also be found of advantage when the gum tread-sections 23 are reversed to change the formation of the spring bracket-arms somewhat, as shown in Fig. 17. 1n this modiiication a pair of bracketarms 29b is formed from one of the wire rods and is bent at the centerof length to provide a cradle wherein the reversed tread of the gum section 22 is supported, the remaining portions of said strand of wire having two de pending spaced loops n formed thereomwhich in service are engaged with the tensionhrin gs 27, the remaining end portions of said wire strand being hooked upon or otherwise secured to the carrier-rings 25, as indicated in Fig. 17.

In Fig. 18 at 29C another modification for the resilient bracket-arms is shown, wherein an elastic metal strip is utilized inthe formation of each arm, said strip being bent to produce two depending spaced loops n and two spring members at each side of each of said loops, the ends of the strips which are bent so as to project toward each other below a flat intermediate portion thereof being secured upon the part on which they bear.

It will be seen from the foregoing description that the essential features of the im provement comprise a plurality of elastic treadsections for a wheel-tire, means for holding the tread-sections in ring form, and resilient arms which serve to elastically retain the composite tread-ring concentric with two spring tension-rings clamped upon each side of a wheel-rim.
